SEOUL (Kyodo) South Korea plans to transfer its extra reserves of boron to Japan to help its neighbor stabilize quake-damaged nuclear reactors, the government said Wednesday.

State-run Korea Hydro & Nuclear Power Co., which operates South Korea's 21 commercial reactors, plans to ship the boron in the next few days, Yonhap news agency reported.

Japan asked South Korea to provide the material, which is vital for stopping fission reactions, after its own stockpile was largely used up at the Fukushima power plant.
